"Generally that is merely a poetic way of saying that a bomb exploded and all hell broke loose. As it is, gunpowder is only known in the lands to the far, far, far, far, far, far, far, far, far, far, far, far, far, far, far, far East (or maybe just West) and they only use it for making pretty pictures in the sky and can’t possibly see it as a method of warfare and killing people, which coincidentally, are both the same thing. Also, hell couldn’t break loose because they, being the trio in the hallway, were already in it. Instead, in this sense the phrase “the world erupted into flame” should not be taken in the poetic sense. Rather, an eruption of flame, albeit a small one, did, in fact, take place."
